IMPROVEMENT IN BASE-BURNING STOVES.

Specification forming part of Letters Patent No. 139,231, dated May 27,1873; application filed February 7, 1873.

' that the draft is downward through the live f fire, whereby the smokeis consume and nothing but a heated gas passes off through the chimney.

This furnace is intended for soft coal, slack,

or the cheapest article of fuel, and consists of a magazine for a supplyof fuel, at the bottom of which is a fire-pot, made broadest at thebasegsfrom the sides of which fire-pot are pipes he heated gases to adrum,

`from which a pipe connects with a chimney.

Ajcold-air draft-space surrounds the magazine, which air is admittedthrough perforations at the base of the magazine, whereby the smoke isdrawn down through the ire and is burned.

The following is a description of its con struction and operation:

In the accompanying drawing, Figure l is a front elevation of theaforementioned furnace. Fig. 2 is a vertical section of the same.

A is a fire-pot, which I make largest at the base, the sides slantin ginward toward the top, the object of which is to prevent the lodgment ofashes or cinders on the sides, thus making itmuch easier for cleaningthe grate. From the top of the fire-pot A rises a magazine, B, whichalso tapers, being smallest at the top. This form overcomes theliability of the fuel clogging in the cylinder, whiizh is4 rom quitelikely in using soft coal or slack.

the sides of the fire-pot rise pipes C C, which connect it with a drum,D, the magazine, the draft from the fire being through said pipes C Cinto the drum, thence to the chimney in the direction of the arrows.

Surrounding the magazine is a jacket or case, E, having an outlet to theopen air at E. At

the base of the magazine, and inside the jack-j` (fait, are perforat'onse e, which admit air to the connection with the top of the magazine, isused for filling the flue, G, at the front of the fire-pot enables thefire to be examined when desired.

The operation is as follows: First, a fire is made in the fire-pot A,the draft-opening E being closed, the draft being made `through thegrate from the ash-pit H beneath. When a good bed of live coals isobtained, the magazine is filled with f elfaud the draft from theash-pit closed tig-ht, andthe draft through E opened, when the smokethat is madel from the burning fuelY must pass through the live fire,and is entirely consumed, so that no smoke can be seen issuing into. thechimney. The drum and the fire-pot both cast oif a great amount of heat.

I claim- A stove provided with a cone-shaped `magazine, B, a fire-pot,A,`of similar form, air-flue 1 E, pipes C, and drum D, so constructedand arranged as to conduct the draft through the live lire, and thusconsume the smoke,.as dei scribed.
